Question

a conical tent is to accomodate 22 persons. each person must have 5m^2 of the space on the ground and 30m^3 of air to breath. find the height of the cone

Answer 1

Answer:

ANSWER

Area of base = 11×4=44 m2

πr2=44 m2

Volume of the cone = 11×20=220 m3

31πr2h=220 m3

Therefore,

πr231πr2h=44220

3h=5

h=15 m

Answer 2

Area of base = 11 × 4 = 44 m2

nr2 =44m2

Volume of cone = 11 × 20 = 220 m3

31πr 2h = 220 m3

Therefore ,

πr 231 πr2h = 44220

3h = 5

H = 15 m
